    Javier Fernandez-Sanguino Pena discovered that updatejail, a component
    of the chroot maintenance tool Jailer, creates a predictable temporary
    file name, which may lead to local denial of service through a symlink
    attack.
    
    For the stable distribution (etch), this problem has been fixed in
    version 0.4-9+etch1.
    
    For the upcoming stable distribution (lenny) and the unstable
    distribution (sid), this problem has been fixed in version 0.4-10.
    
    We recommend that you upgrade your jailer package.
